SCINTILLATION CAMERA (in Japanese)
An important problem in the scintillation camera is determine exactly a scintillation image, in such a way that the photopeak scintillation caused by gamma-rays is reproduced as a point flash of light on the cathode ray tube screen in the same relative position as the original scintillation in the crystal. In this case, Compton process and scattered gamma -ray pulses are eliminated by the pulse-height selector, and only photopeak pulses passes through the selector. The amount of light accepted by a bank of photomultiplier tubes is not equal at any point on the surface of crystal. For the purpose of avoiding such fault, in an improved scintillation camera nine photo-multiplier tubes are arranged in a certain formation. By the aid of the matrix circuit the (X,Y) coordinate can be determined, then a flash point is reproduced on cathode ray tube. (T.F.H.)
